protected void btnUpload_Click（object sender，EventArgs e）
{
// Coneection String默认为空
string ConStr =;
//文件上传控件的溢出保存到ext，因为
//有两种类型的exation .xls和.xlsx的Excel
string ext = Path.GetExtension（FileUpload1.FileName）.ToLower（）;
//获取文件的路径
string path = Server.MapPath（〜/ MyFolder /+ FileUpload1.FileName）;
//将文件保存在服务器的MyFolder中
FileUpload1.SaveAs（path）;
Label1.Text = FileUpload1.FileName +\的数据显示在GridView中;
//检查extantion是.xls还是.xlsx
if（ext.Trim（）==。xls）
{
//该文件的连接字符串，其中包括.xls
ConStr =Provider = Microsoft.Jet.OLEDB.4.0; Data Source =+ path +;扩展属性= \Excel 8.0; HDR =是; IMEX = 2 \;
}
else if（ext.Trim（）==。xlsx）
{
/ /该文件的/连接字符串，其中包含.xlsx
ConStr =Provider = Microsoft.ACE.OLEDB.12.0; Data Source =+ path +;扩展属性= \Excel 12.0; HDR =是; IMEX = 2\ ;
}
//进行查询
string query =SELECT * FROM [Sheet1 $];
//提供连接
OleDbConnection conn = new OleDbConnection（ConStr）;
//检查连接状态是否关闭如果关闭
//打开连接
if（conn.State == ConnectionState 。已结束）
{
conn.Open（）;
}
//创建命令对象
OleDbCommand cmd = new OleDbCommand（query，conn）;
//创建数据适配器并将数据输入dataadapter
OleDbDataAdapter da = new OleDbDataAdapter（cmd）;
DataSet ds = new DataSet（）;
//将Excel数据填充到数据集
da.Fill（ds）;
//设置网格视图的数据源
gvExcelFile.DataSource = ds.Tables [0];
//绑定gridview
gvExcelFile.DataBind（）;
//关闭连接
conn.Close（）;
}

<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="btnUpload" runat="server" OnClick="btnUpload_Click" Text="Upload" />
<asp:Label ID="Label1" runat="server">
<asp:GridView ID="gvExcelFile" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None">
<alternatingrowstyle backcolor="White" forecolor="#284775">
<editrowstyle backcolor="#999999">
<footerstyle backcolor="#5D7B9D" font-bold="True" forecolor="White">

<sorteddescendingheaderstyle backcolor="#6F8DAE">
protected void btnUpload_Click(object sender, EventArgs e)
{
//Coneection String by default empty
string ConStr = "";
//Extantion of the file upload control saving into ext because
//there are two types of extation .xls and .xlsx of Excel
string ext = Path.GetExtension(FileUpload1.FileName).ToLower();
//getting the path of the file
string path = Server.MapPath("~/MyFolder/"+FileUpload1.FileName);
//saving the file inside the MyFolder of the server
FileUpload1.SaveAs(path);
Label1.Text = FileUpload1.FileName + "\'s Data showing into the GridView";
//checking that extantion is .xls or .xlsx
if (ext.Trim() == ".xls")
{
//connection string for that file which extantion is .xls
ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
}
else if (ext.Trim() == ".xlsx")
{
//connection string for that file which extantion is .xlsx
ConStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
//making query
string query = "SELECT * FROM [Sheet1$]";
//Providing connection
OleDbConnection conn = new OleDbConnection(ConStr);
//checking that connection state is closed or not if closed the
//open the connection
if (conn.State == ConnectionState.Closed)
{
conn.Open();
}
//create command object
OleDbCommand cmd = new OleDbCommand(query, conn);
// create a data adapter and get the data into dataadapter
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
//fill the Excel data to data set
da.Fill(ds);
//set data source of the grid view
gvExcelFile.DataSource = ds.Tables[0];
//binding the gridview
gvExcelFile.DataBind();
//close the connection
conn.Close();
}
but it should read open office spread sheet data not ms office excel sheet data how can i do this
